An Oklahoma teen who thought it would be funny to fool her boyfriend into believing she was pregnant suddenly got serious halfway into her own April 1st prank and ditched the gag in favor of stabbing him in the neck instead.

Authorities in Wagoner County say Tori Wheeler, 18, started off by telling her beau Derek Bauer that she was with child, and followed that up by brandishing a knife in his direction and threatening him with physical harm.
